4 Applications & efficiency Main applications Typical applications are those requiring high torque within a small size. The hydraulic motor is essential for rotations where: mechanical solutions are complex or even impossible; electrical or pneumatic power sources are not available; environments are dangerous (i.e. risk of explosion or extreme temperatures). Examples of use Mowers: drive of grass cutting blade, where mechanical solution would be too complicated or impossible; Blowers: compressor drive; Wheel drive of undercarriages for construction equipment (motor installed on planetary gearbox); Industrial of marine winch drive; Fan drives.

Definition & advantages 5 Definition of function Hydraulic motors transform hydraulic flow into rotating speed and hydraulic pressure into mechanical torque. Motor rotating speed is proportional to the flow which is supplied to it. Torque produced is proportional to the hydraulic pressure the motor receives. Advantages of LEDUC motors High quality materials and workmanship. The design choices highlighted below ensure the remarkable reliability and long service life of LEDUC motors. Choice of increased bearing capacity for longer service life. No gears between plate and rotating barrel yields reduced noise levels. 7 piston design, ensuring excellent rotating smoothness and constant torque. Reinforced seals to withstand back pressure on motor drain return lines. High pressure oil injection on piston heads: this reduces friction, heat and wear. iston heads engaged into barrel: no risk of piston / plate separation. Design and manufactured with motor barrel and valve plate automatically aligned. This guarantees long service life (because no radial mechanical stress).

6 Operating conditions reparation of the motor Before start-up, the motor must be filled with oil. Filtration of the hydraulic fluid The service life of the motors depends greatly on the quality and the cleanliness of the hydraulic fluid. We recommend minimum cleanliness as follows: NAS 1638 class 9, SAE class 6, ISO/DIS 446 class 2/18/15. For fluids at very high temperatures 194 to 239 F (9 to 115 C), we recommend a minimum cleanliness class of 19/17/14 according to ISO 446. Rotating speeds Minimum rotating speed to obtain continuous rotation is 2 rpm (however, in certain conditions, the motor can run at speeds as low as 5 rpm). Maximum rotating speed is given for each model of motor. The fluid LEDUC motors are designed for use with mineral based hydraulic fluid. Using other fluids is possible but may require a modified motor. lease contact us with details of fluid. Recommended viscosity: Ideally: between 15 and 4 cst; Maximum range: between 5 and 16 cst. Fluid viscosities as a function of temperature Installation positions LEDUC motors are made to operate in all positions (see details on page 52). Operating temperatures As standard, LEDUC motors are fitted with FKM seals (Viton ). Operating temperatures: from -13 to 239 F (-25 to 115 C). As an option, HYDRO LEDUC proposes NBR seals, for operating temperatures from -4 to 176 F (-4 to 8 C). Temperature C IMORTANT NOTE: Before start up, ensure the motor is filled with hydraulic fluid: See section on installation and start-up, page 52.

Operating conditions 7 Direction of rotation The motors rotate clockwise or counter-clockwise depending on the direction of hydraulic flow entering the motor. Clockwise rotation (CW) Counter-clockwise rotation (CCW) T1 T1 T2 T2 B A B A Drain pressure It is essential to drain the motor, T1 or T2, to avoid excessive pressures on the shaft seal. Maximum acceptable internal pressure depends on motor rotating speed. However, following these guidelines will avoid problems during operation: Maximum internal pressure (int ) regardless of rotating speed (continuous): 4 bar; Maximum internal pressure (int ) regardless of rotating speed (peak): 5.5 bar; Minimum pressure in the motor housing: must be greater than ambient (external) pressure (ext ).

8 Determination Calculating the right motor How to determine the correct motor for your application Calculations using usual mechanical units: N = rotating speed (rpm) C = Torque (N.m) Δ = ressure difference between A and B (bar) Cy = Displacement cc/rev Q = Flow (l/min) η = Efficiency (%) 1. Torque supplied by the hydraulic motor Cy x Δ Theoretical torque = = Cth 2 π Torque C = Cth x ηmotor For example: a 5 cc/rev motor with a Δ of 25 bar will supply a theoretical torque of 2 N.m. Average global efficiency of the motor is 9%, actual torque is thus: 18 N.m). 2. Rotating speed of the motor The rotating speed of the hydraulic motor depends on the flow Q which goes through it, and on the displacement of the motor. Q N = x 1 Displ.

The hydraulic pump 2 is capable of operating at pressure up to 35 bar. 1. Calculating the displacement of the hydraulic motor: Cth = Disp. x Δ 2 π thus Disp. = 35.9 cc/rev In the LEDUC range, choose a motor with a displacement of 32 cc/rev or 41 cc/rev. 2. Calculating the flow Q which the pump needs to supply: Q = N x Disp. 1 Corresponding flow: For 32 cc/rev motor, Q = 12.8 l/min For 41 cc/rev motor, Q = 16.4 l/min

5 Options Accessories FLUSHING VALVE LEDUC CODE: VBS 9118 Used to create flow to cool the motor. This valve is essential for all intensive uses of motors and contributes to long service life. The valve takes some hydraulic fluid from the return connection port (low pressure) and reinjects it into the motor housing. This is then evacuated via the motor drain line. Flushing valves are only available for use with motors with side ports (N1 or Q1).

Options Accessoires 51 ATEX CERTIFICATION LEDUC motors are certified ATEX As standard, all LEDUC motors are classed in Group II category 2 D TX. On request, motors may be supplied for Group II category 2G and Group II category D T4. As all the motors must be delivered unpainted (risks due to static electricity), it is necessary to pay attention to the risks of corrosion. Explanation Group II category 2 means it is possible to operate in an ATEX 1 zone (probable gas atmosphere) or ATEX 21 zone (probable dusty atmosphere). G = May operate in a gas zone. D = May operate in a dusty atmosphere. TX = Maximum surface temperature. recautions regarding ATEX It is necessary to check the following recommendations: The operating temperatures of the motors must be guaranteed by the end user. The machines on which our products are assembled should be ground-connected (static electricity). Check all parts connected to the motor for conformity with ATEX. Markings on motors The marking of our product will be: Group II category 2GD c TX (where TX replaces T3 and T4). Our products are TX registered (based on product surface temperature) and can therefore be certified T4 or T3 according to the following recommendations (hot area). Surface temperature T4 275 F (135 C) for fluid temperature < 158 F (7 C). T3 392 F (2 C) for fluid temperature < 23 F (11 C). Example of ATEX marking on motors CE II 2 GD c TX HL1 If you have different requirements, please contact us. IMORTANT NOTE: ATEX certification does not apply to motors fitted with speed sensor, nor to the drainless motors. Options Accessories

Drainless motor option 53 Drainless motor bent axis hydraulic motor HYDRO LEDUC is now able to offer drainless motors for either single direction of rotation or bi-directional use, under certain conditions and on request (giving details of your application). ADVANTAGES No drainline needed Only two hose lines are required: supply line and output. The motor is drained through the return line. It is fitted with a high pressure lip seal. CHARACTERISTICS Working speed: lease consult our Technical Department with details of your applications. Max. pressure on the return line: 25 bar. Schematic drawing for use in single direction of rotation Schematic drawing for bi-directional use A B For bi-directional applications, the motor is fitted with an accumulator integrated in the back piece, to compensate possible pressure peaks in the housing (for example from rapid change in direction).
